I would think everyone here should be concerned - the protocol seems not only more processor efficient (theoretically faster), but more privacy (and security) -inclined as well, as I understand it:
https://en.wikipedia.org/wiki/IPv6-to-IPv6_Network_Prefix_Translation <- there's an interesting reference link there, and Part 2 has a paragraph that states:
"This means that, should you find yourself having to manage the integration of two separate networks and routing domains following a merger, you’ll be able to route between them without any renumbering (or tricky NAT configuration). But, again, this only works if the ULA subnets have been properly generated using the recommended randomization function." which is exactly what we're doing, managing the integration of our LANs with the greater WAN of the internet itself, right?
And maybe this article (that updates the reference link articles I mentioned) will bring everything together in our heads:

Brilliant, although perhaps Pastebin would have saved you having to tediously cut up the debug output into separate PMs!
However, I think I can see the problem..
Code:
+ sqlite3 /opt/etc/wireguard.d/WireGuard.db INSERT into session values('wg22','Start','1647599856');
+ sqlite3 /opt/etc/wireguard.d/WireGuard.db SELECT auto FROM servers WHERE peer='wg22';
+ [ Y == S ]wg22 is not defined as a Site-to-site 'server' Peere.g. Your
wg22 'server' Peer is set AUTO=Y rather than AUTO=S
Code:
E:Option ==> peer
Peers (Auto start: Auto=P - Policy, Auto=S - Site-to-Site)
Server Auto Subnet Port Annotate
wg21 Y 10.50.1.1/24,fd36:7ef1:2add:aa88::1/64 11501 # RT-AX88U (IPv4/IPv6) Server 1
wg22 Y 10.50.2.1/24,2a02:c7f:f0c3:1010::1/64 11502 # RT-AX88U (IPv4/IPv6) Server 2Can you issue
Code:
e = Exit Script [?]
E:Option ==> peer wg22 auto=sNow restart wg22 and hopefully the cron job should be created.

Thanks for the interesting link! The main reason for using ULA+NPT6 would be to use Wireguard server with a dynamic wan prefix. Unfortunately the links does not address this.
Altough as it seems NPT6 is available in our routers and hoping for some good results from @archiel as to wheither it is working or not. If it is working we should, by no doubt, use that instead of NAT6 (masquarade).
But the command is abit tricky and when trying to write script to automatically do this I realized they would need something like wgm "Expand_Ipv6" and "Compress_Ipv6" and eventually to the conclution that I should leave it to more experienced scripters. I don't know if it is in the stars that it comes into wgm, but it is were it belongs.
Currently our routers don't seem to route ula to wan at all, packages don't even reach forwarding, so unwillingly we reached the same conclusion as in your links. Right now the only option is to use some global address (could be from reserved space, like aa-space). Altough a non-optimal solution it would basically solve the problems in the link. But for how long until there are conflicts?
Edit: aah, now I get why I sometimes get the "you have ipv6 but your device does not seem to want to use it" message... My lan is on ula... makes perfect sense now!

LOL, indeed! I didn't realize until the third copy/pasteBrilliant, although perhaps Pastebin would have saved you having to tediously cut up the debug output into separate PMs!
Ahh, I see. I think I changed it quite some time ago to wg22.
In any case, wg_manager doesn't allow the auto=2 for wg22:
Code:
E:Option ==> peer wg22 auto=s
***ERROR Invalid Peer Auto='s' wg22'Can I rename it to wg21? Or maybe just re-create new on both ends. It's wg22 at both Home and Cabin.

Can you try setting

Ok, did the above, restarted server and now cru l shows the WireGuard_ChkDDNSwg22 entry.
Thanks!

FYI, just changed my lan prefix to: aaff:a37f:fa75:1::1/64 instead of fdff:a37f:fa75:1::1/64 and I went from good/mediocre score to great score on test sites. Even the google ipv6 test seems satisfied. Jackpot!you're most welcome! I like to help...or nudge a train of thought here or there

Jason's recommended script appears to blindly resolve the DDNS when the connection is dormant (which makes sense?) presumably in an attempt to ensure that the next packet exchange will resolve correctly.
I guess there is no need to write the message - so I'll suppress it in the next release.

Updated Ipv6 server part for dynamic wan ips, it is now confirmed working:
https://github.com/ZebMcKayhan/WireguardManager/edit/main/README.md#setup-wg-server
Put in the NPT6 part as well but mostly for reference and still experimental.

Thanks,Uploadedwireguard_managerBeta v4.16b6
Minor bug fix, but should (finally) improve the statistics metrics displayed on screen for 'client' Peers.
P.S. @ZebMcKayhan In fixing the comment/tag update issue, this may also fix the inability to delete your 'server' Peers, together with suppressing (by default) the re-resolv DDNS Syslog message although they can now be optionally issued.

I feel as if "critical mass" might be achieved shortly, if I'm reading things right.
I wonder if WireGuard's originator might be interested enough to poke his head in at this point...

I've experienced weird issues like this before...it should always work in a script but in some cases doesn't, so I've reverted to old-skool slower code

This is a big deal, being able to follow ISP-initiated WAN IP changes - it (if I understand things correctly) does away with needing to set up DDNS tunneling, and maybe even FQDNs with HTTPS certs. Possibly (and this is a stretch) get out from behind IPv4 CGNAT
This would make your router (or should we just call it our WG server?) much more private I think, and tunnel more secure. (basically you're your own VPN)
I'm just not sure how you've accomplished making this change, where in the router GUI to find it; by selecting/configuring Native IPv6, I don't get the option: it auto-populates...I may be missing something. Is it a command line thing, why you've added scripts? (the thought occurred when reading the github that anyone with a /48 should know how to amend the scripts themselves if they've come this far) (it's not the best time of day for me to use my brain on this stuff)
(NOTE: to anyone trying to follow this pages-long thread, STOP. Go to the README on Zeb's github. it's all very clear there, laid out in easy progression)
